Microsoft Graph Subscribed SKUs

Microsoft Graph Subscribed SKUs is the API/resource that lists the Microsoft 365/Azure AD license subscriptions your tenant owns. When you call GET /subscribedSkus, it returns each license plan (SKU) with its identifiers (skuId, skuPartNumber), seat counts (prepaidUnits and consumedUnits), subscription status (enabled, suspended, warning), and the included service plans. This lets apps and admins inventory licenses, map SKU IDs to human-readable plans, check capacity before assigning licenses, spot suspended or trial subscriptions, and build usage or compliance reports. In practice, you read subscribed SKUs to choose the right skuId, then use Graphs license assignment endpoints to add or remove that license for users or groups.
